Gear selecting and shifting mechanism of automotive transmission

Abstract

The invention provides a gear selecting and shifting mechanism of an automotive transmission, which belongs to the technical field of automotive transmissions and solves the technical problems of complicated structure, large occupied space, inconvenience for arrangement, difficulty in assembly, high cost and the like of an existing gear selecting and shifting mechanism of an automotive transmission. The gear selecting and shifting mechanism of the automotive transmission comprises a gear shifting finger, a gear selecting and shifting shaft and an interlocking plate sleeved on the outer side of the gear shifting finger, the gear selecting and shifting shaft sequentially penetrates through a shell, the interlocking plate and the gear shifting finger, the interlocking plate is positioned between the gear shifting finger and the shell, the interlocking plate and the shell are fixed circumferentially along the gear selecting and shifting shaft, a gear selecting self-locking structure is arranged between the gear shifting finger and the shell, and a gear shifting self-locking structure is arranged between the gear shifting finger and the interlocking plate. The gear selecting and shifting mechanism has the advantages of simple structure, small occupied space, convenience for arrangement, easiness in assembly, low cost and the like.

Description

technical field [0001] The invention belongs to the technical field of automobile transmissions, and relates to an automobile transmission, in particular to a gear selection mechanism in the automobile transmission. Background technique [0002] In order to output the torque and speed suitable for each working condition to the driving wheels of the car, it is necessary to shift gears. Due to the vibration of the car during gear shifting, if the shifting mechanism jumps or loses gears, it will affect driving safety. Therefore, a self-locking device has appeared, and its function is to prevent the transmission from automatically disengaging and shifting gears by itself. The traditional self-locking device realizes self-locking by utilizing the friction between the shift fork shaft and the self-locking steel ball during gear shifting. [0003] In recent years, some self-locking devices for shifting gears that are different from traditional automobile transmissions have also ap...

Problems solved by technology

However, its structure is still the same as the traditional structure, and the gear selection and shifting self-locking mechanism is assembled to the shifting mechanism, which is complicated, takes up a lot of space, is not conducive to layout, is difficult to assemble, and has a high cost.

Moreover, the gear selection self-locking and gear shifting self-locking of the gear selection mechanism need to design a special structure on the shift fork shaft, etc., which increases the occupied space, and the manufacturing cost is high and the assembly is complicated.
